Cometech Series I Grips | Uniaxial, Biaxial, Adjusted & Screwed Collet | GR-I010 / GR-I01A / GR-I020 / GR-I030 | Rod, Small Diameter & Precision Alignment Testing
- Series I grips are precision positioning and alignment grips for multi-axis tensile and compression testing — covering uniaxial X-shift (GR-I010), biaxial X/Y-shift (GR-I01A), single-axis adjusted grip (GR-I020), and screwed collet grip for rods and small diameter materials (GR-I030); all designed for precise specimen centering before load application.
- GR-I010: 60×60mm platen, ±25mm X-shift, 0–200°C, 1463g; GR-I01A: 60×60mm platen, ±25mm X/Y-shift, 0–100°C, 2452g; GR-I020: 500N, 88mm jaw, 80mm thickness, 0–100°C, 2256g; GR-I030: 500N, 1–9mm jaw, 100N min. load cell, 0–100°C, 621g.
- Suitable for flat specimen compression alignment (GR-I010/I01A), thick or irregular specimen alignment (GR-I020), and rod/small diameter material tensile testing (GR-I030).
- Compatible with Cometech universal testing machines; platform-mounted designs for X and/or Y shift adjustment.

Overview
Cometech Series I grips are precision alignment fixtures for specimens requiring exact center alignment before load application — eliminating off-axis bending error in tensile, compression, and peel tests on brittle materials, adhesive joints, rods, and composites.
GR-I010 and GR-I01A are platen-style alignment grips providing ±25mm X-shift (uniaxial) or independent X and Y shift (biaxial) across a 60×60mm contact area, suitable for flat specimen compression tests at up to 200°C and 100°C respectively.
GR-I020 handles thicker and more irregular specimens with an 88mm jaw and 80mm thickness capacity, while GR-I030 is a dedicated screwed collet grip for rods and small diameter materials (1–9mm) at up to 500N load — providing secure, centered gripping without crushing slender specimens.
